The Nigeria Immigration Service (NIS) has issued a circular titled "Abolition of Re-entry Visa" indicating that the Minister of Interior has approved the discontinuance of re-entry visas for purpose of re-entering Nigeria for expatriates that have valid residence permits.

The Immigration Act provides that no person other than a citizen of Nigeria shall accept employment (not being employment with the Federal or State government) without the consent in writing of the Director of Immigration; or either alone or in partnership with any other person, practice a profession or establish or take over any trade or business or register or take over a limited liability company without the consent in writing of the Minister.
